'Baptize' in the Bible

So they asked him, “Why then do you baptize if you aren’t the Messiah, or Elijah, or the Prophet?”

“I baptize with water,” John answered them. “Someone stands among you, but you don’t know Him.

I didn’t know Him, but He who sent me to baptize with water told me, ‘The One you see the Spirit descending and resting on—He is the One who baptizes with the Holy Spirit.’
